Health and Safety at every stage
Health and Safety is of the utmost importance on every site that we work on, as it not only concerns all of our staff members, but everyone else in the vicinity; including you, your neighbours and even passers-by. Due to the nature of our work, there is always the risk of injury or even death, as ladders, tools and various other materials can be hazardous. Basement conversions in particular are technically very challenging, and can pose a number of different risks, with a large proportion of these projects in London regularly failing safety checks. Unguarded excavations and unprotected floor openings represent serious dangers to all those concerned. That is why our staff are expertly trained and will always diligently adhere to all necessary Health and Safety procedures and issues.
British Standard 8102:2009
British Standard 8102:2009 is the ‘Code of practice for protection of below ground structures, substructures, understructure against water from the ground’. In essence, it is the primary design guide for structural waterproofing and groundworks in the UK, with the recent update being released in November 2009. If you are producing a waterproofing design, or you have advisors that are designing on your behalf, this document should cover every consideration possible. If you have further questions in regards to the BS8102, please feel free to contact us.
An intuitive basement construction process will ensure your project will run smoothly and is monitored and overseen by managing director, Andi Pepaj, and managed by our project managers on site.
APT Renovation has over 17 years experience in underpinning and basement excavation adhering to basement standards to a very high-level finish.
You will be advised by your Project Manager who will be on site all day, every day and will be your first point of contact.
Tanking, or ‘Type A barrier protection’ (BS8102 definition), is a specific form of waterproofing of underground rooms and understructures, although it is a common term applied to all forms of waterproofing. In the true sense of the word, tanking means blocking water out of a structure by employing a barrier product which is installed internally, sandwiched within, or applied externally to a structure. Tanking is still widely used and applied in building industry, but has declined in popularity in recent years where retrofit protection is required for existing basements.
Waterproofing is a very important aspect in a basement and cellar conversion, particularly as the UK experiences a very high level of rainfall each year. A lack of waterproofing will eventually result in damp on walls, which not only looks bad, poor odours can be detrimental to your hygiene as well, and can cause significant damage to the paint job, the plastering and the finish. Worse still, damp can also lead to breathing problems and other health issues, so it is something that should be eradicated immediately.
APT Renovation Design & Build has had huge success over the years in waterproofing with Delta Membrane Systems and pumps. For basement waterproofing, the Delta sealed system ensures that all membranes are expertly sealed and secured, as well as any protrusions or crevices. Delta Systems are incredibly effective in dealing with adverse water conditions and especially basements that have the propensity to flood. There is a 30-year guarantee on all Delta membrane systems
